Experimental study on a multi-evaporator refrigeration system with variable area ratio ejector

This paper describes an experimental study on a multi-evaporator refrigeration system (MERS) with conventional pressure regulating valve (PRV) and variable area ratio ejector. Some key performance indicators such as cooling capacity, power consumption and ejector entrainment ratio were evaluated by...

Some key performance indicators such as cooling capacity, power consumption and ejector entrainment ratio were evaluated by switching operating modes, adjusting superheat and tuning ejector spindle and so on.
